Simple sample:

docker run -d -p 99:22 jennava/ubuntu-ssh:trusty

docker logs <CONTAINER_ID>

You will see an output like the following:

========================================================================
You can now connect to this Ubuntu container via SSH using:

    ssh -p <port> root@<host>
and enter the root password 'F45uIVUM789y' when prompted

Please remember to change the above password as soon as possible!
========================================================================

In this case, F45uIVUM789y is the password allocated to the root user.

Done!

Setting a specific password for the root account

If you want to use a preset password instead of a random generated one, you can set the environment variable ROOT_PASS to your specific password when running the container:

docker run -d -p 99:22 -e ROOT_PASS="mypass" jennava/ubuntu-ssh:trusty

Adding SSH authorized keys

cd ~/.ssh/
ssh-keygen -t rsa -C "[email protected]"

If you want to use your SSH key to login, you can use AUTHORIZED_KEYS environment variable. You can add more than one public key separating them by ,:

docker run -d -p 99:22 -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" jennava/ubuntu-ssh:trusty
